A suitable shoulder is provided on the pin near the nail engaging end 15thereof and preferably takes the form of an annular notch or groove forthe purpose of engaging the edge of the opening 28 in retaining finger25, when the pin is substantially withdrawn from the bore 11 of thebarrel and when the retaining member is in binding engagement with thepin, as will be readily understood, thus reventing accidental withdrawalof the pin f r o'm the barrel. 1

This construction possesses another ad vantageous feature, due to theresiliency of the finger 25, in' cushioning to some degree the blows ofthe hammer on the head 16of the driving pin, when the latter reaches apoint near the upper end I) of the barrel, thus offering considerableresistance to any blow which would tend to drive the head 11 against theend I) ofthe barrel and mar the woodwork against which the end a of thebarrel may,

engage. Suitable indicating marks 18 are provided on the driving pin 14to co-operate with the edge of the opening 28 to indicate the positionofthe nailengaging end 15 of the driving pin 14.

In some instances the thumb 29 may be eliminated, and the pressure ofthe handle of theuser in grasping about thebarrel 10 will cause the edgeof the opening 28 to bind against the pin, orvice-versa.

In Figures 4 and 5 is shown a modified frictional means engaging the pin14. This modified means comprises a piece of resilient material, bent toform a resilient loop 31, as

prising a barrel, a driving pin slidable within the barrel, a resilientspring loop mounted on the barrel at the end thereof through which saidpin is inserted to normally exert frictional pressure against the sideof the pin to hold the same in adjusted positions in the barrel, andmeans for retaining said loop in position.

2. A tool of the character described comprising a barrel, a driving pinslidable within the barrel, a resilient spring loop mounted on thebarrel at the end thereof through whichsaid pin is inserted to normallyexert frictional pressure against the side of the pin to hold the samein adjusted position in the barrel, and a removable cap holding saidloop in position on said'e'nd of the pin.

clearly shown, disposed in a thimble-capl member 32 having a centralopening therein 33. The cap is threaded or otherwise se-' Y cured on theend I) of the barrel and the pin 14 passes through the opening 33' andthrough thespring loop 31. V The ends at andy of the loop member arebent upon themselvesto engage the side walls of the cap to produce aresilient contraction in the loop 31 which is designed to be of lessdiameter than the diameter of the pin, and thereby partially obstructsthe opening 33 in the cap and exerts a, frictional bindingpressure onthe side of the pin. In this form of theinvention the groove 30 is usedon the pin with which the loop 31 will engage and prevent withdrawal ofthe pin from the barrel.

From the above it will be obvious that a very economical and efficientmeans has beenprovided for frictionally binding the driving broken.
